Nance added, "A celebrity of LeBron’s stature gets many money grubbing claims all the time and this is no different.”

But Leicester is firing back -- telling TMZ, "This not a money grubbing case. This is a very carefully considered effort to resolve a pressing issue that should be handled seriously by LeBron James' attorney."

Leicester concluded, "There is absolutely no relationship between what is happening in LeBron's life and the timing of the filing of this lawsuit ... the timing of the filing of this lawsuit is a product purely of legal considerations."
